In Chapter 3, Ariely discusses the zero price effect; namely, that due to the
emotional surge of getting something for free, humans ignore the downsides of a zero cost item. He states, "We can use FREE! To drive social policy....If health is your concern, focus on early detection as a way to eliminate the progression of severe illnesses. Want people to do the right thing—in terms of getting regular colonoscopies, mammograms, cholesterol checks, diabetes checks, and such? Don't just decrease the cost (by decreasing the co-pay). Make these critical procedures free." (pp. 68-69) Question: please list three FREE! interventions that would drive social policy toward enhanced aggregate health. For each intervention, provide a brief rationale for why the free intervention makes good policy.
